Kokichi Ouma is one of the main antagonistic characters of Danganronpa: V3, and his title is the Ultimate Supreme Leader. Fitting his appearance, Kokichi often acts very innocent and child-like, sometimes appearing genuine but in most situations doing so to use his looks to his advantage. He is sometimes shown to have child-like excitement and innocence, as he gets very excited about "cool" new things in a child-like excitement and often acts playful. However, don't let that deceive you. He is an elusive, intelligent, perceptive, and manipulative person who tells countless lies. Kokichi considers lying a big part of himself and a way of life, appearing either unwilling or unable to stop it and even claiming that his body is made up of 70% lies. He frequently claims one thing, only to shortly retract and say he was just lying, making him very untrustworthy. Sometimes his lies are very obvious, but at other times it can be near impossible to tell whether or not he is telling the truth. He's even able to tell when a person is lying because of how often he lies himself.

Kokichi is one of the first of his classmates to become a remnant; first being Tsumugi, then Kaito, and then him. Since they're some of the first members, Kaito and Kokichi are always butting heads in the form of a prank war - it would usually be inatiated by Kokichi ppre-despair, but as things became stranger, the duo seemed weirdly... equal and mean. They'd always play cruel pranks, send hurtful things that would cut them to their core, and it would get increasingly worse as the days go on. But oddly, they'd brush things off as if it was a harmless funny prank. But by the time people caught on... it was already too late. Pre tragedy, he would kill his  members of DICE as an act of submitting to the despair, murdering the only people he'd see as his family. During the tragedy, Kokichi's lies about becoming the supreme leader of a large secret society finally becomes true. He would rebuild DICE from the ground up, his new goal to be spreading despair across the globe. As for his personality, Kokichi would tend to bounce around with his emotions, likely to mirror Junko herself. However, some habits just won't ever die, as Kokichi is still the trickster and conniving liar like he was before he was a remnant.

For his voice, I'm definitely leaning towards something close to his English voice, but really also want to encapsule the more playful and teasing side like his Japanese VA does. While his JPN VA plays off of Kokichi's cute/innocent face and builds up his endearing personality and small touches of innocence, he makes him seem like a little kid playing games. As for his ENG VA, he focuses on Kokichi's more sarcastic trickster demeanor.
